Answering the question. I REALLY hope that the mother opens her eyes. Of course it is not bad to be kind but that doesn’t mean you have to be a pushover or naive. She already has the enough proof to understand the kind of people her sister and niece are. I really wish the mother to be one of the strengths of our girl and not her weakness
Wtf? A pot calling the kettle black. You are calling the wrong person that lady. Can't wait for the character development in the mom because she'll die at this rate.
As with option 1 of the answer, I'm apprehensive, but I do think (and hope) she would be able to handle it. Her daughter did go through being banished to small village so that her mom could open up her eyes.
I'm assuming the mother will survive this, though I can't tell how apart from pure luck. Then again, maybe she'll learn the way her daughter did and she'll manage.
